Yes - as it applies to gaining access to the same table a second time.

What I provided will allow access to any table. It is a general way to
exercise any SQL statement. IOW's it does not use Dabo special tools to
access data.
But you have me confused.
As I understand your needs you have a simple parent->child relationship. Where
'dist' is a child of 'stat'. So when you say you want to display all the
records in 'dist' unfiltered I don't understand the reason. Maybe you do not
realize that it is possible to display all the filtered records at once?
I will make this up but I believe it is a typical situation that presents it's
self to programmers daily. You have a parent (lets say 'stat') table and you
have a child ('dist') table. This relates to other parent->child relationship
i.e Customers -> orders.
With Dabo you would setup the relationship just like we have already done.
Next you would create two grids, Grid1 would contain the list of parents
(stat) and Grid2 would contain the filtered records of the child (dist).
As you move to different rows in Grid1 the records will automatically change
in Grid2 to match whatever row (record) is in Grid1.
I realize in your case you are not using Dabo's UI but the data still does the
same thing (as above). So all that would be required would for you to
retrieve the data to display - is to move the record pointer in the parent
(stat) and automatically the child (dist) record/s will come available for you
to display. You would display data using your javascript or the use of your
wsgi system.
